Biology, Mathematics
This paper derives a full numerical EBT scheme for age-structured, two-sex population model (Fredrickson-Hoppensteadt model), which consists of three coupled hyperbolic partial differential equations with nonlocal boundary conditions, which is the first step towards extending the EBT method to systems of structured population equations.
